返回具有给定RGB/HEX值的像素的坐标

import cv2

def find_pixels_with_rgb(image_path, target_rgb):
    # 加载图像
    image = cv2.imread(image_path)

    # 转换为RGB颜色空间
    image_rgb = cv2.cvtColor(image, cv2.COLOR_BGR2RGB)

    # 获取图像尺寸
    height, width, _ = image.shape

    # 遍历图像的每个像素
    pixel_coordinates = []
    for y in range(height):
        for x in range(width):
            # 获取像素的RGB值
            rgb = image_rgb[y, x]

            # 比较RGB值
            if rgb == target_rgb:
                pixel_coordinates.append((x, y))

    return pixel_coordinates

# 示例用法
image_path = "path/to/image.jpg"
target_rgb = (255, 0, 0)  # 目标RGB值为红色
result = find_pixels_with_rgb(image_path, target_rgb)
print(result)
